Renalase in peritoneal dialysis patients is not related to blood pressure, but to dialysis vintage

摘要

The prevalence of hypertension in peritoneal dialysis (PD) patients ranges from 29% to 88%, and blood pressure (BP) controlis often very poorin this group (1-3). Multiple factors are involved in BP control, including water retention and salt intake, increased activity of vasoconstrictive systems, decreased activity of vasodila-tory systems, increased intracellular calcium, increased arterial stiffness, oxidative stress, hyperparathyroidism, erythropoietin, inflammation, sleep apnea, renovascular disease, and overactivation of the sympathetic nervous system (1,4-6).
